quick help with shaping metal rods
Hi everyone new member here and I'm really stuck for this little side project that I'm doing. Essentially i need to attach a hand wheel to a square socket. I have a square socket with dimension of 10mm x 10mm and a handwheel with a bore diameter of 10mm with a little square coming out of the side (see pic attached). I bought a square metal square rod off ebay with dimension 10mx10m but being from a dodgy seller it has a off cut with a flat end at the end (see attach pic). so the problem I'm having is the square rod seems a little bit big to fit into the square socket hopefully a little filing i can get it to fit. But the main issue is how do i transform a square rod into a circle. I have attached 3 photos to show the socket, metal rod and the hand wheel. any help would be great !!!! thanks eveyrone

Hi k0e,
Welcome
That "bar" sure looks like a cheap carbide tipped lathe tool of come sort.
Well you could file it round... how long will the round section be?

Hi K0e,
The easy way would be to put it in a four jaw on a lathe and turn it down to fit the hand wheel. Then file the square to fit the socket.
But I'm guessing you don't have a lathe. Maybe an engineering shop or school could help, unless you have a friend with a lathe.
Also depending on how much load there is going to be when rotating the handwheel you are going to need a key slot putting into the round bit of your bar. You will also need a key to fit. Fortunately that is an easy filing job. If the load is fairly light a flat filed on the round bar where the grub screw tightens onto may be enough.
HTH.Best Regards:

Doubt any of my friend has a lathe. Does make life a bit easier with it ! the load is fairly light dont imagine a lot of resistance would be involved in the work that i want to do. So you saying if i dont have a lathe handy, to maybe drill a hole through the rod and handwheel and tighten with a grub screw? Cause theres no hole for the grub screw.

A quick and dirty way would be to file square to fit and weld threaded rod to the end of the square which has been cut to length. Attach the wheel to the rod with a couple of nuts. This presumes you can get access to a welder. Easier than a lathe at least.

If you have no luck with it,I could make one for you.
It would either require you coming to St Marys with the parts so as to make to sample or supplying a detailed drawing (correct sizes) and postage.

Think I might need your help pipeclay. Seems like I can't PM you through my account don't have access to it. If you don't mind emailing me your detail( address, convenient time, phone number ) to my email address [email protected] that would be wonderful. I'll have to drop in to st Mary to show you the parts.
Cheers

I have to say, I'm really curious as to what project uses a hand wheel on some sort of Kitchen Aid appliance - especially when said appliance is still in the shop!
Bout the best theory I can come up with is using the right angle drive out of some kind of mixer for..... Something....

Hi K0e,
Based on your previous post if the bar is TC forget using it. It is so hard a drill won't go through it. The hand wheel is probably intended to be secured to a shaft by a nut and locked with a keyway so you have a positive drive. So yes you could drill a hole through the hand wheel over the keyway and use a grub screw bearing onto the key.
I think you would be better off talking to pipeclay.Best Regards:
